CVE-2026-93558 Io.netty/netty-codec-http: netty: unbounded per-connection queue growth in websocketserverextensionhandler leads to denial of service

A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive...

CVE-2026-93491 Io.netty/netty-codec-http: netty: denial of service via unbounded httpservercodec http/1.1 pipeline queue

A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leading to unbounded heap memory consumpti...

CVE-2026-93573: Inconsistent Interpretation of HTTP Requests

A flaw was found in Netty's HTTP/1.1 decoder. This vulnerability allows a remote attacker to bypass Transfer-Encoding header validation by splitting the Transfer-Encoding field across multiple headers, with the last field containing a non-final transfer coding like gzip or deflate. This bypass ca...

CVE-2026-93574: Inconsistent Interpretation of HTTP Requests

A flaw was found in Netty's netty-codec-http component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an...

AsyncHttpClient's unbounded HTTP/1.1 response decompression enables a decompression-bomb denial of service

Impact With automatic response decompression enabled the default, the HTTP/1.1 path decompresses response bodies with no limit on the total output size. A hostile or compromised server, or an attacker who can change a response in transit, can send a small compressed body that inflates without bou...

sanic chunked trailer request smuggling allows hidden second request execution

Description Sanic's HTTP/1.1 chunked-body handling does not fully consume the trailer-part after the terminating 0\r\n chunk. Because of that, attacker-controlled bytes left in the connection buffer after the first chunked request can be interpreted as the start of a new HTTP request on the same...
